Abstract

L'invention concerne un circuit qui relie de manière automatique et uniforme la plus forte (ou la plus faible) de deux alimentations à une sortie. Le circuit ne s'expose pas à une chute de tension d'une diode lorsque les deux alimentations sont à peu près au même niveau de tension et l'alimentation non utilisée n'entraîne pas de courant d'attente. Un transistor à couplage transversal et des onduleurs à couplage transversal sont utilisés.
